摘　　要：利用磁调制原理构成直流电流传感器 ,并由此研制了直流系统绝缘在线检测装置。本装置与直流系统完全独立 ,不影响直流系统正常工作且直流电流传感器结构简单、分辨率高。由于采取了固定偏差设计 ,实时检测偏差基准 ,提高了装置的抗干扰能力。适用于发电厂与变电站直流系统绝缘的在线检测。The paper presents the DC transducer by magnetic modulation. By this theory, A DC system Sulation monitor is develop which is independent to DC system. The DC transducer is simple in structure but has high discriminability. With strong antidisturbance for fixed deviation design, it's suitable to be applied in power plant and Substation.
